Improvements in the regioselectivity of alkylation reactions of stannylene acetals

The regioselectivity of benzylation of stannylene acetals of trans-diols on pyranose rings is improved by performing the reaction in benzyl bromide, for instance, for methyl 4,6-O-benzylidene-2,3-O-dibutylstannylene-α-D-glucopyranoside, the ratio of 2-O-b

Preparation and calculated conformations of the 2'-, 3'-, 4'-, and 6'-deoxy, 3'-O-methyl, 4'-epi, and 4'- and 6'-deoxy-fluoro derivatives of methyl 4-O-alpha-D-galactopyranosyl-beta-D-galactopyranoside (methyl beta-D-galabioside).

The glycosyl chlorides of the 3-O-methyl (6) and 4-deoxy-4-fluoro (8) O-benzylated derivatives of D-galactopyranose and 2,3,4,6-tetra-O-benzyl-D-glucopyranose were condensed with methyl 2,3,6-tri-O-benzoyl-beta-D-galactopyranoside to give, after deprotect

ALKYLATION OF METHYL 4,6-O-BENZYLIDENE-α-D-GALACTOPYRANOSIDE

The partial alkylation of methyl 4,6-benzylidene-α-D-galactopyranoside in dimethylformamide and dimethyl sulfoxide in the presence of barium oxide and hydroxide is described.It has been shown that methylation and benzylation lead predominantly to the 3-al
